4.3 Main Menu Settings
Sensor Mode:
Soil mode configures the sensors to read the height from the spray nozzles to the ground.
Crop mode will read the height from the spray nozzles to the top of the crop canopy. Hybrid
mode will use both the distance measured to the crop canopy and the distance measured to
the ground to determine the crop height. Hybrid mode will create a virtual crop canopy using
historic crop height information preventing the boom from tracking down into the crop when
the crop canopy is thin or in areas of downed crop or wheel tracks.
To change sensor modes, press twice from the run screen. The screen will display either
"SOIL", "CROP", or “HYBRID”. Use the buttons to change the setting.
Sensitivity:
The sensitivity can be adjusted from 1 to 10, with 5 being the default setting. A lower number
will reduce the system sensitivity. Higher settings will speed up the response and also create a
greater demand on the hydraulics.
To change the sensitivity, press the button once from the run screen. The current
sensitivity will be displayed. Use the buttons to change the setting.
Target Height:
The target height is the height that the operator would like the boom to be set at when
spraying. When operating in soil mode, the target height is measured from the spray nozzles to
the soil. In crop mode the target height is measured from the crop canopy to the spray
nozzles. In Hybrid mode the target height is measured from the crop canopy, or in the absence
of a crop canopy, to the virtual crop canopy. The target height can be changed from the run
screen while the system is in automatic mode by using the
buttons.
Severe Terrain Mode:
Some sprayers have the ability to fold in the boom tips and spray with only the inner sections of
the boom. If the sprayer has this ability and is equipped with a five sensor system (severe
terrain kit) then this feature may be used when spraying with the tips folded in.
Press from the run screen until "Tips on" is displayed. Use the buttons to turn it on
or off. By turning the tips off, the two outer sensors on the wings will be disabled and only the
inner wing sensors will be used to control the height.
When the tips are turned off the run screen will show a lower case "a" in automatic to indicate
the outer sensors are turned off. The Severe Terrain Mode is defaulted to “Tips on” and will
return to "Tips on" anytime the power is cycled. When spraying with the full boom, the setting
should be "Tips on" to allow the outer sensors to operate again.
